In today's society, cars have become a necessary means of transportation for every household, but some novice drivers still have a smattering of knowledge about the problems in the use of cars, so how much do you know about some common sense of car maintenance? Zhongyuan Auto Xiaobian answers your questions:
1. The battery should be kept in a fully charged state
The battery on the car is the most vulnerable to "injury" if the car is not driven for a long time. The lead-acid battery on the car will have self-discharge even if it is not used. Generally, the self-discharge will reduce the capacity by more than 1% every day and night. If there are still electrical appliances working on the car or the technical condition of the battery is not good, the self-discharge rate will be greatly increased.When the battery capacity is less than 70% of the standard capacity, the surface of the plate inside the battery will produce sulfide, which will cause irreversible damage, and the service life of the battery will be greatly shortened, or even scrapped in advance. Therefore, before the car stops, be sure to keep the battery in a fully charged state, turn off all electrical appliances, and remove the negative wiring of the battery, which can reduce the discharge rate of the battery and prolong its service life.If you don't want to pull out the negative pole, it's better to check the battery every two weeks, such as whether the electrolyte height is 10 to 15 mm higher than the plate, and add distilled water if it's not enough.
2. Replace the oil regularly
The oil on the car, like the engine oil, must be replaced regularly, such as brake oil, gearbox gear oil, booster oil and antifreeze. These oils are closed and circulated in their respective systems. Each oil has a visual standard scale. We can observe the height and quality of the oil level through these scales. If each pipeline, rubber sleeve and sealing gasket are not damaged, the oil will not be missing, but its fineness will deteriorate with time and cycle times.If we do not change the oil regularly, the oil will not be able to maintain a good state of vehicle parts, and at the same time, our safety will be threatened.
3. The more oil you add, the better.
If too much oil is added, the engine will be damaged, the pressure will increase, the crankshaft oil seal will be damaged, resulting in oil leakage, black smoke and high temperature, and the oil will enter the cylinder and burn, producing black glue, which will damage the cylinder. Whether too much oil or too little oil is added, it will affect the machinery. Therefore, the daily refueling of machinery should be strictly in accordance with the prescribed standards to reduce the occurrence of mechanical failures.
4. Clean the engine compartment regularly.
After the car is used for a long time, the engine compartment is usually full of dust, then the owners need to clean up regularly, otherwise it will affect the normal heat dissipation of the engine. Severe poor heat dissipation can cause the gasket to leak oil. However, it should be noted that the engine compartment is absolutely not washable.
5. Car headlights
Automobile headlights should be replaced according to the use of 50000 kilometers or about 2 years. Automobile lamps are used for lighting, especially in the process of driving at night, which is equivalent to the eyes of the car. Zhongyuan Auto Xiaobian reminds us that if there is a problem with the headlights, the consequences will be unimaginable, so we should keep it in mind.
6. Tire
No matter how durable the tire is, attention should be paid to its replacement. The replacement cycle of a tire is 50,000 to 80,000 kilometers. Once there is a crack on the side of the tire, it is a sign of danger! Replace it in time!
